Description

A kind of assisted standing seat for the elderly

technical field

The invention relates to medical nursing equipment, in particular to an auxiliary standing seat for the elderly.

Background technique

Today's society is gradually aging, and the elderly have become a hot spot of social concern. Now there are more and more empty nesters, how to make these empty nesters better live alone is our concern. Standing is a crucial factor affecting independence in activities of daily living in older adults. As they get older, many older adults who are able to walk remain trapped in chairs because they lack the ability to stand. At the same time, some elderly people have difficulty standing up due to bone and other reasons. The elderly cannot stand up from sitting and will need the care of others, which not only seriously affects the physical and mental health of the elderly, but also imposes a huge burden on the family and society.

Further, a support plate is arranged between the second backrest support plate and the bottom plate, the support plate is arranged on the bottom plate through a support column, and the lower end of the vertical guide rail is fixedly connected to the support plate.

Further, the power drive assembly includes a first motor and a second motor, the first motor is arranged on the bottom plate, and is connected to the pedal through a first screw rod, the first screw rod is parallel to the translation direction of the pedal, the The second motor is connected with the backrest through a second screw rod, and the second screw rod is parallel to the lifting direction of the backrest.

Further, the top of the vertical guide rail is provided with a motor support plate, the second motor is provided on the motor support plate, and the second screw rod penetrates the motor support plate, the first backrest support plate and the second backrest support from top to bottom in sequence. plate, and the end is movably connected with the support plate.

Further, the seat includes a seat support plate and a seat plate arranged on the seat support plate, the seat support plates are arranged in pairs, one end is hinged with the lower end of the backrest, and one end is hinged with the top end of the seat support push rod.

Further, the seat support push rod is a retractable push rod. When adjusting the seat support push rod to adapt to the user's leg length, the second motor is independently driven to fine-tune the upper and lower positions of the backrest to ensure that the seat is level.

Further, armrests are provided on both sides of the seat to prevent the user from falling down from the side of the seat due to balance problems when sitting.

Further, the power drive assembly is started and stopped synchronously through the controller, including a first motor and a second motor, both of which are connected to the controller, and can be controlled individually or simultaneously. The controller is provided with a control program, The controller can be controlled through the APP, or a button to control the corresponding state of the controller can be set on the seat, which is convenient for the user to operate.

Compared with the prior art, the present invention has the following beneficial effects:

1. The lifting component is matched with the supporting component. The lifting component helps the elderly get up and stand slowly. The supporting component not only supports the weight of the elderly, but also tilts the seat and bends the legs to move the legs closer to the body. The relative angle between the calf and the thigh is from 90° gradually approaches 180°, which is in line with the relative relationship between the legs and the body when a person gets up, so that the elderly can stand alone.

2. The pedals are provided with pulleys, and there is no need to set slide rails on the bottom plate, and the device structure is simple.

3. The backrest is in the form of a frame, which can ensure the vertical movement of the backrest. The polished rod running through the backrest is the main force-bearing component, which bears the force of the second screw rod to drive the backrest movement and the gravity of the entire second motor, and can be used Provides greater support for the back.

4. The seat support push rod is a retractable push rod, which can adjust the height of the seat, so that the elderly of different heights can sit comfortably on the elderly auxiliary standing seat.

5. When the motor is stationary, the first screw rod and the second screw rod will not rotate due to the large static torque of the motor, which can ensure that the backrest will not move downward due to gravity, so that the seat can be limited to a certain height. Ensure the safety of users.
